Hydroponics Introduction to Hydroponics
Terms • Hydroponics: – growing of plants in a solutions of nutrients, without soil • Substrate: – substance in which plant takes root
General Facts • Any plant can be grown in hydroponics. • Almost any system can achieve acceptable growth. • Small scale hydroponics is different from large scale.
General Facts • Hydroponics contributes to understanding plant growth. • Very few commercial producers in U. S. –Many in Europe and Canada • Techniques highly technical, many experimental
Hydroponic Requirements • Best possible light • 50% or more humidity • Day temp = 75 deg. • Night temp = 65 deg.
Other Requirements • All essential elements needed – Obtained from nutrient solution (fertilizer water)
Commercial Production • Minimum of 100, 000 sq ft • Will be able to tell conditions of nutrient solution by looking at the plants
Advantages of Hydroponics § Reduced land cost § More control over growing environment § Reduced pesticide use § Year-round supply § Alternative to urban sprawl
Commercial Hydroponics Greenhouse
Disadvantages of Hydroponics • Start-up costs high • Management – few know how • Labor requirements intense • Technology - advanced
Special attention to nutrient solution is a must. Special equipment for growing
